About
Glass Weight Calculator is a free online tool that calculates the exact weight of a glass panel instantly — no signup, no manual formulas. Enter the glass type, shape, dimensions and thickness, and it returns the weight in kilograms and pounds, plus the panel area and volume. It supports rectangular, square, triangular, circular, semi-circular, elliptical, round rod and custom shapes, switches seamlessly between metric (mm, cm, m) and imperial (in, ft), and uses the correct density for each material — float, tempered, laminated, low-iron, borosilicate, acrylic and polycarbonate included. Architects, glaziers, builders, interior designers, aquarium builders and DIY users use it to check frame and hinge load ratings, plan lifting and transport safely, and avoid overloading structural supports. The site also includes a standard glass weight chart (2mm–19mm, kg/m² and lbs/ft²), a thickness guide, density references, and companion tools for glass deflection, glass thickness, plastic weight, and pipe weight and volume. Features: Instant weight in kg and lbs, plus area and volume; 8 shapes; multiple glass types with correct densities; metric and imperial units; standard weight chart for 2mm–19mm glass; completely free, no signup, works on mobile. Pricing: Free — $0, no signup.
